DESCRIPTION:
Here we introduce this exceedingly rare dinosaur tooth from Elrhaz Fm. It is an authentic tooth of Nigersaurus, herbivorous sauropod rebbachisaurid dinosaur that lived during the Aptian stage of the Early Cretaceous of modern-day Niger. Small for a sauropod, Nigersaurus was about 9 m (30 ft) long, and had a short neck. It weighed around 4 t (4.4 short tons), comparable to a modern elephant.

Observations: This Nigersaurus tooth is especially impressive because it is so well preserved, with its enamel showing a pretty nice dark black color. It also shows well-developed feeding wear. A truly exceptional specimen. It is very rare to find Nigersaurus teeth of this quality.

The Elrhaz Formation is mostly made up of fluvial sandstones. A diverse assemblage of fossil animals has been recovered, bony fish, turtles, several genera of crocodylomorphs (Anatosuchus, Araripesuchus, Sarcosuchus, and Stolokrosuchus), undescribed ornithocheirid pterosaurs, the theropod dinosaurs Eocarcharia, Kryptops, Suchomimus, and an undescribed noasaurid (possibly Bahariasaurus), the sauropods Nigersaurus and an undescribed titanosaurian (Malawisaurus), and the iguanodontians Lurdusaurus and Ouranosaurus.
